Dumb question. Why should someone ever buy a HDD nowadays?

This will blow your mind, but datacenters still buy tapes. It's just stupid cheap. In the future, chemical storage by DNA or something similar might play the same role for cold storage.

I don't get why we research DNA as storage.

It is sensible as fuck, deteriorates quickly, is slow to write and read...

Only advantage it's bio-compatibility

The information density is insane, both volumetric and by mass.

I sort of agree, though. With current methods it seems like it would probably be just as easy to record information in a synthetic polymer.
